Which of the following are valid names for the given triangle? Check all that apply.
A. LMZ
B. ZMC
C. LCM
D. LMD
E. MLZ
F. ZML

A.

E.

F.

Step-by-step explanation:

Those are the three points connected on the triangle.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
